The utility model has the effect of fixing the slit cardboard during transportation.

[0004] Similar to the flattening structure of a slitting machine, the hardness of the fabric will increase due to factors such as the high density of the fiber structure and the uneven thickness of the fibers. Different types of fibers have different hardnesses, such as cotton, polyester and nylon. Some of the fibers are relatively hard. Hard fabrics will not be easily cut by the knife during slitting, and will produce burrs and uneven cuts during slitting.

[0005] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a flattening mechanism for a slitting machine is proposed. Utility Model Content

[0006] The purpose of the utility model is to provide a flattening mechanism for a slitting machine. Due to the high fiber structure density of the fabric, uneven fiber thickness and other factors will lead to an increase in the hardness of the fabric, and different types of fibers have different hardnesses, such as cotton, polyester and nylon, some of which are relatively hard in themselves. Hard fabrics will make the fabrics difficult to be cut by the knife during slitting, and will produce problems such as burrs and uneven cuts during slitting.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a flattening mechanism for a slitting machine, comprising a base, a feeding roller, a heating assembly and a feeding roller, a support rod is arranged on the right side of the upper end surface of the base, and the support rod is arranged in two groups, and the feeding roller is arranged at the upper end between the two groups of support rods, a fixed plate is arranged at the center of the upper end surface of the base, and the fixed plate is arranged in two groups, and transmission rollers are arranged at the upper ends of the opposite surfaces of the two groups of fixed plates, and the transmission rollers are arranged in several groups, and the outer surfaces of the several groups of transmission rollers are arranged with conveyor belts, and a first motor is arranged on the outer side of one group of the fixed plates, and the heating assembly is arranged on both sides of the upper end surface of the conveyor belt, and limit plates are arranged at the centers of the upper end surfaces of the two groups of fixed plates, and lower pressure rollers are arranged on the opposite surfaces of the lower ends of the two groups of limit plates, and load-bearing rods are arranged on the left sides of the two groups of fixed plates, and the feeding rollers are arranged on the opposite surfaces of the upper ends of the load-bearing rods, and the feeding rollers are arranged in two groups, and a second motor is arranged on the outer side of one group of the load-bearing rods.

[0008] Furthermore, the heating assembly includes a mounting seat, a flattening roller, a heating element and a stainless steel roller. The mounting seat is arranged on both sides of the upper end surfaces of the two groups of fixed plates, and the opposite surfaces of each two groups of mounting seats are provided with flattening rollers. The outer surface of the flattening roller is provided with a heating element, and the outer surface of the heating element is sleeved with a stainless steel roller.

[0009] Furthermore, the outer surfaces of several groups of the driving rollers are respectively in contact with the inner surface of the conveyor belt, and the positions of several groups of the driving rollers are arranged in parallel and at intervals.

[0010] Furthermore, outer surfaces of the two groups of feed rollers are provided with a rubber layer, and one end of one group of feed rollers protruding from the load-bearing rod is connected to the output end of the second motor.

[0011] Furthermore, one end of the transmission roller protruding from one group of the fixing plates is connected to the output end of the first motor, and outer surfaces of the two groups of rubber layers abut against each other.

[0012] Furthermore, the outer surface of the stainless steel roller is in the shape of hole-shaped triangles arranged at equal intervals, and the inner surface of the stainless steel roller abuts against the outer surface of the heating component.

[0013] Compared with the prior art, the utility model has the following beneficial effects: by setting a heating component, the flattening mechanism of the slitting machine has a heating effect, which can heat the fabric. The fabric after heating treatment by the heating component is softer and easier to be cut by the slitting machine knife, reducing the cutting resistance, improving the cutting precision and accuracy, ensuring that the size and shape of the cut fabric meet the requirements, and by heating and then flattening, the curling of the fabric can be effectively prevented. The specific contents are as follows:

[0014] A heating component is provided, and two groups of heating components apply a more uniform flattening method to the fabric. The flattening roller is limited by the mounting seat. The flattening roller converts electrical energy into thermal energy through the heating element on the outer surface, thereby transferring heat to the stainless steel roller. The stainless steel roller is responsible for contacting the surface of the fabric. The fabric becomes soft when heated, making it easier for the slitting machine to cut, and the soft fabric after heat treatment will be less stretched during the cutting process, thereby reducing the breakage and damage of the fabric, and when the fabric is flattened during the heating process, the heat energy will make the fabric soft and easier to shape, which helps to reduce the internal stress of the fabric, keep it flat and not prone to curling. Through the combined effect of heating and flattening, the fabric can be made more stable and soft during the cutting process, reducing the deformation and curling of the fabric.

DETAILED DESCRIPTION

[0020] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0021] like Figures 1 to 4As shown, a flattening mechanism for a slitting machine includes a base 1, a feed roller 3, a heating assembly 8 and a feed roller 12. A support rod 2 is arranged on the right side of the upper end surface of the base 1. The base 1 supports the entire structure, provides an installation platform, and provides necessary support and connection. Two groups of support rods 2 are arranged. The feed roller 3 is arranged at the upper end between the two groups of support rods 2. The two groups of support rods 2 limit the feed roller 3, and the feed roller 3 is responsible for conveying and providing fabrics.

[0022] A fixed plate 4 is arranged at the center of the upper end surface of the base 1. Two groups of fixed plates 4 are arranged. The fixed plates 4 are used to fix and support the transmission part of the mechanism, and play a connecting and supporting role. Transmission rollers 5 are arranged at the upper ends of the opposite surfaces of the two groups of fixed plates 4. The transmission rollers 5 are arranged in several groups. Several groups of transmission rollers 5 are used to transmit power and motion, drive the operation of the conveyor belt 6, and realize the transmission and movement of materials. The outer surfaces of several groups of transmission rollers 5 are arranged with conveyor belts 6. The conveyor belts 6 are used to carry and transmit fabrics, so that the fabrics can be transmitted and processed inside the mechanism. A first motor 7 is arranged on the outer side of one group of fixed plates 4. The first motor 7 provides The driving power drives the transmission rollers 5 to rotate. The outer surfaces of several groups of transmission rollers 5 are respectively in contact with the inner surfaces of the conveyor belt 6. One end of the transmission roller 5 protruding from one group of fixed plates 4 is connected to the output end of the first motor 7. When the first motor 7 is started, one group of transmission rollers 5 is driven to rotate, thereby driving the conveyor belt 6 to move. While the conveyor belt 6 is moving, it drives the remaining transmission rollers 5 to rotate, thereby achieving a transmission effect. The positions of several groups of transmission rollers 5 are arranged in parallel and spaced manner. The positions of multiple groups of transmission rollers 5 are arranged in parallel and spaced manner, so that the conveyor belt 6 can smoothly transmit materials between each transmission roller 5;

[0023] The heating assembly 8 is arranged on both sides of the upper end surface of the conveyor belt 6. The heating assembly 8 heats the fabric and flattens it. The heating assembly 8 includes a mounting seat 801, a flattening roller 802, a heating element 803 and a stainless steel roller 804. The mounting seat 801 is arranged on both sides of the upper end surface of the two groups of fixed plates 4. The mounting seat 801 supports and fixes the flattening roller 802. Flattening rollers 802 are arranged on the opposite surfaces of each two groups of mounting seats 801. The flattening roller 802 provides a rotation function and flattens the fabric through the heating element 803 and the stainless steel roller 804. The outer surface of the flattening roller 802 is provided with a heating element 803. The heating element 803 surrounds the outer surface of the flattening roller 802 to provide heat energy, heat the material, and ensure uniform heat energy. The heat is released to the surface, making the fabric soft and easier to shape. The outer surface of the heating element 803 is sleeved with a stainless steel roller 804. The outer surface of the stainless steel roller 804 is in the shape of a hole-shaped triangle and is arranged at equal intervals. The inner surface of the stainless steel roller 804 is in contact with the outer surface of the heating component 8. The stainless steel roller 804 with a hole-shaped triangle surface is used to transfer heat energy and pressure to the fabric, so as to better transfer heat energy to the surface of the fabric. A limiting plate 9 is provided at the center of the upper end surface of the two groups of fixed plates 4. The limiting plate 9 limits the lower pressing roller 10. The opposite surfaces of the lower ends of the two groups of limiting plates 9 are provided with a lower pressing roller 10. The lower pressing roller 10 provides a limiting and pressing function between the two groups of heating components 8 to prevent the pressure between the two groups of heating components 8 from being relaxed.

[0024] The left side of the two sets of fixed plates 4 is provided with a load-bearing rod 11, which supports and carries the two sets of feed rollers 12 to ensure the stability and working effect of the feed rollers 12. The feed rollers 12 are arranged on the opposite sides of the upper ends of the load-bearing rods 11. There are two sets of feed rollers 12. The two sets of feed rollers 12 convey the flattened fabrics to the slitting section of the slitting machine for subsequent processing. A second motor 13 is arranged on the outer side of one set of the load-bearing rods 11. The outer surfaces of the two sets of feed rollers 12 are provided with a rubber layer 121. One set of feed rollers One end of the roller 12 protrudes from the load-bearing rod 11 and is connected to the output end of the second motor 13. The outer surfaces of the two groups of rubber layers 121 abut against each other. One group of feed rollers 12 is driven to rotate by the second motor 13. Since the rubber layers 121 on the outer surfaces of the two groups of feed rollers 12 abut against each other, when one group of feed rollers 12 is driven to rotate, it drives the other group of feed rollers 12 to rotate, so that the fabric continues to be transported forward from the clamping point between the feed rollers 12, thereby driving the fabric to pass through the flattening mechanism.

[0025] In summary, if Figures 1 to 4As shown, the flattening mechanism for the slitting machine has a base 1 that supports and bears the weight of the upper structure, and two groups of unloading rollers 3 at the support rods 2 provide the fabric supply, and then the fabric passes through the surface of the conveyor belt 6. When the first motor 7 is started, one group of transmission rollers 5 between the two groups of fixed plates 4 is driven to rotate, thereby driving the conveyor belt 6 to move accordingly. While the conveyor belt 6 is moving, it drives the remaining transmission rollers 5 to rotate, so that the conveyor belt 6 achieves a transmission effect;

[0026] The fabric is heated and flattened by one of the heating components 8, and then pressed down for the second time by the lower pressure roller 10 between the limit plates 9, and then transported to another group of heating components 8 for heating and flattening by the movement of the conveyor belt 6, and then clamped by two groups of feeding rollers 12 between two groups of load-bearing rods 11 to transport to the next slitting section. Since the rubber layers 121 on the outer surfaces of the two groups of feeding rollers 12 abut against each other, when one group of feeding rollers 12 is driven to rotate by the second motor 13, it drives the other group of feeding rollers 12 to rotate, thereby driving the fabric to continue to be transported forward from the clamping point between the feeding rollers 12, thereby driving the fabric to pass through the flattening mechanism, and the flattening roller 802 is limited between the two groups of mounting seats 801 by the rotating shaft, and by contacting the surface of the fabric, it drives the fabric to continue to be transported forward along with the movement of the conveyor belt 6;

[0027] The heating element 803 contains resistance wires. When current passes through these resistance wires, a resistance heating effect is generated, causing the heating element 803 itself to heat up and release heat energy. Once the heating element 803 is heated, it will transfer the heat to the contacting stainless steel roller 804. The stainless steel roller 804 has a heat transfer and heat conduction effect, and will absorb the heat energy released by the heating element 803, so that the temperature of the stainless steel roller 804 itself increases, and through the contact between the stainless steel roller 804 and the fabric, the heat will be transferred to the fabric, causing the fabric to be heated and softened.
